使用angularjs和ng-repeat从JSON数据创建表

Question

我有以下数据作为JSON:

{
  "Workout1": {
    "Name": "First",
    "Rounds": [
      {
        "Exercises": [
          {
            "Name": "Exercise1",
            "Repeat": 10
          },
          {
            "Name": "Exercise2",
            "Repeat": 10
          },
          {
            "Name": "Exercise3",
            "Repeat": 10
          }
        ]
      },
      {
        "Exercises": [
          {
            "Name": "Exercise1",
            "Repeat": 20
          },
          {
            "Name": "Exercise2",
            "Repeat": 20
          },
          {
            "Name": "Exercise3",
            "Repeat": 20
          }
        ]
      },
      {
        "Exercises": [
          {
            "Name": "Exercise1",
            "Repeat": 30
          },
          {
            "Name": "Exercise2",
            "Repeat": 30
          },
          {
            "Name": "Exercise3",
            "Repeat": 30
          }
        ]
      }
    ]
  }
}

我想将它显示为带有angularjs和ng-repeat的html表.这样我得到下表:

<table class="table">
    <tr>
        <th>Round1</th>
        <th>Round2</th>
        <th>Round3</th>
    </tr>
    <tr>
        <td>10 Exercise1</td>
        <td>20 Exercise1</td>
        <td>30 Exercise1</td>
    </tr>
    <tr>
        <td>10 Exercise2</td>
        <td>20 Exercise2</td>
        <td>30 Exercise2</td>
    </tr>
    <tr>
        <td>10 Exercise3</td>
        <td>20 Exercise3</td>
        <td>30 Exercise3</td>
    </tr>
</table>

我的问题是html表是基于行的.我可以通过我的轮次进行ng-repeat迭代,然后通过我的练习进行迭代但是为了创建一个表格,我需要每个练习的第一个,然后是每个练习的第二个,依此类推.

有人可以帮我解决这个问题吗？

PS.如果您对json中的这些数据有更好的布局,我们欢迎您的建议,我是json(和angularjs)的新手.

Answer 1

您正在寻找的解决方案是在Angular的官方教程中.在本教程中,使用Angulars $ http服务从JSON文件加载电话.在下面的代码中,我们使用$ http.get来加载保存在phones目录中的phones.json文件:

var phonecatApp = angular.module('phonecatApp', []);   
phonecatApp.controller('PhoneListCtrl', function ($scope, $http) {
 $http.get('phones/phones.json').success(function(data) {
$scope.phones = data;
}); 
$scope.orderProp = 'age';
});

然后我们遍历手机:

<table>
  <tbody ng-repeat="i in phones">
    <tr><td>{{i.name}}</td><td>{{$index}}</td></tr>
    <tr ng-repeat="e in i.details">
       <td>{{$index}}</td>
       <td>{{e.foo}}</td>
       <td>{{e.bar}}</td></tr>
  </tbody>
</table>

在普通表中使用简单的方法创建动态标题和单元格:

<table width="100%" class="table">
 <thead>
  <tr>
   <th ng-repeat="(header, value) in MyRecCollection[0]">{{header}}</th>
  </tr>
 </thead>
 <tbody>
  <tr ng-repeat="row in MyRecCollection | filter:searchText">
   <td ng-repeat="cell in row">{{cell}}</td>
  </tr>
 </tbody>
</table>

MyApp.controller('dataShow', function ($scope, $http) {
    //$scope.gridheader = ['Name','City','Country']
        $http.get('http://www.w3schools.com/website/Customers_MYSQL.php').success(function (data) {

                $scope.MyRecCollection = data;
        })

        });
